NIFS Healthy Living Blog

By this point, everyone has heard that exercise is good for health. The fitness industry has been growing significantly over the past decade. As of 2017, there were more than 200,000 health and fitness clubs worldwide, which is up from nearly 130,000 clubs in 2009. Clearly, fitness is becoming a huge part of peoples’ lives. But why are we seeing this massive growth in the industry, and in what ways is it improving health?

The Physical Benefits

The physical benefits of increased activity include the following.

Increased Muscle Mass

A well-known benefit to working out is increased muscle mass. This alone has so many benefits to your health besides the visual appeal that people seek. Muscle is a huge driver for metabolism. In fact, it takes so much energy to maintain muscle mass that having more of it increases metabolism significantly, even at rest.

Improved Bone Health

Most people hit peak bone mass in early adulthood. After we hit our peak, our bone density begins to decline. Several factors go into how much we build before we hit our peak and how fast we fall once over that peak. And of course, exercise is a huge factor in this. Weight-bearing activity that forces you to challenge gravity is huge in preserving or even building bone density by breaking down the bone so it can build back even stronger.

Better Sleep

Exercise can improve sleep quality by expelling built-up energy. Another way sleep improves is the cycle of body temperature brought on by exercise. During activity the temperature increases; once activity has stopped the temperature gradually decreases, causing chemicals to be released that promote drowsiness.

Increased Energy and Stamina

In the short term, exercise increases blood flow throughout the body to improve energy. Over time, exercise causes improvements in cardiovascular health, allowing the heart to pump more oxygen-rich blood throughout the body, therefore increasing energy.

Reduced Cholesterol

When exercise, weight loss, and dietary intervention are combined, the LDL (bad) cholesterol levels decrease while HDL (good) cholesterol levels increase.

Decreased Risk of Chronic Diseases

If you’ve ever heard the phrase “exercise is medicine,” it will be no surprise that exercise actually reduces the risk of chronic diseases. Various things happen in the body to cause this, but the most important is that by getting active, the chances of developing Type 2 Diabetes, some cancers, stroke, heart disease, and more are drastically reduced.

Increased Coordination and Balance

By staying active, people learn how to be more coordinated and balanced. Motor control over movements becomes more natural the more it is practiced, and will translate to real-life scenarios. In the long run, especially through aging, this is beneficial to help prevent falls and the negative consequences, such as fractured bones, that come along with them.

The Mental Benefits

The mental benefits of increased activity include the following.

• Stress relief
• Positive mood
• Improved mental alertness
• Reduced anxiety and depression
• Improved self-esteem
• Increased cognitive function

Most of these improvements occur due to the increased blood flow to the brain, which acts on the hypothalamic-pituitary-adrenal (HPA) axis. This area of the brain interacts with several other regions, including the limbic system, hippocampus, and amygdala, which are correlated with motivation, mood, and responses to stress. Other noted improvements may be explained by providing distraction, improving self-efficacy, and increasing social interaction. Research shows that exercise can improve cognitive function by promoting neuroplasticity. By staying active throughout adulthood and senior years, cognitive decline can be prevented.

Although many mechanisms go into this complicated process, one thing that is known is that the rate of neurogenesis, or the production of new neurons, is greatly increased by exercise. This may be the result of increased blood flow to the brain during exercise, with an abundance of oxygen and nutrients.

Other Benefits

A lot of benefits that come from exercise can be measured or researched. Some benefits are harder to measure but still occur. We learn how to set realistic yet challenging goals, learn the discipline needed to accomplish those goals, and learn more about ourselves. We can gain a better understanding of how much we can push ourselves and improve our mind-body connection.

How Much Should You Work Out?

The current Physical Activity Guidelines for Americans outlines the recommended amount of activity for different age groups. Adults should do at least 150 to 300 minutes of moderate-intensity aerobic exercise, or 75 to 150 minutes of vigorous aerobic exercise a week. Most health benefits can start to be seen at the minimum amount; however more benefits are seen beyond 300 minutes of activity a week. Adults should also do some type of resistance-training exercise at least two days of the week.

At NIFS, we have multiple group fitness classes every day to help you reach your goals and hit the minimum requirements. Check out the group fitness schedule for 30–60-minute classes to help you achieve at least 150 minutes of exercise a week.

Throughout your life, you will come across times and situations that are tough, making you feel as though getting through it all is inconceivable and hopeless. There are more traditional ways to deal with these ups and downs of life, such as therapy, but there are other ways to overcome stress in life that can be as easy as taking a walk, shooting some basketball, or even lifting weights.

Forget Your Worries: Emotional Benefits of Exercise

There seems to be something about exercise that allows us to forget our worries and deal with our stresses while also improving our lives through wellness and fitness. With as much stress as we see in people's lives today, it would seem as though fitness would stand out as a blessing to anyone who wants to make their life better. Because this isn’t always the case, you can start as slow and as basic as needed to make sure you are getting the right exercise at the right amount at the right time.

The Anxiety and Depression Association of America has determined that exercise is essential for good mental well-being and that the benefits go beyond just reducing stress. Improved mood, increased energy, better sleep, reduced anxiety, and improved self-esteem all are payoffs too.

Get Your Endorphins Going

You might have heard of endorphins. They are the hormones that are released from the brain and nervous system and into your body. We feel good when endorphins are released into our bodies. This can happen as a result of almost anything that stimulates your brain, ranging from riding a rollercoaster to seeing your favorite band perform. With fitness, the same endorphins can be released through exercise, giving you similar feelings. We call this the “runner’s high.” You don’t have to be a runner to achieve this feeling, but exercise is the key ingredient, however you decide to score those endorphins.

Thomas’ Tips for Getting More Active

• Start small, start smart. Take a walk around the neighborhood or with friends after work at the mall. Walking is definitely exercise and has many benefits. .
• Do activities you like to do. If you are trying to keep this fitness and wellness going for a long time, you’d better like what you are doing (at least some of the time).
